SAFETY- ENVELO P.

SPECIFICATION forming part of Letters Patent No. 603,969, dated May 10, 1898.. Ap lication filed Ju1124,1897. Serial No. 642,102. (No model.)

To all whom it may concern:

Be it known that 1, JOHN W. RILEY, of Ogden,:in the county of Weber and State of Utah, have invented certain new and useful Improvements in Safety-Envelops; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make'and use the same.

This invention relates to safety-envelops; and it consists of the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

The object of the invention is to provide means for sealing an envelop that cannot be disconnected without detection and wherein the parts are simple and effective in their construction and operation and comparatively inexpensive in the cost of manufacture.

In the accompanying drawings, Figure 1 is a plan View of a blank embodying the invention. Fig. 2 is a perspective view of the envelop arranged for sealing. Fig. 3 is a section on the line x 00, Fig. 2.

Referring to the drawings, wherein similar numerals of reference are employed to indicate corresponding parts in the several views, the numeral 1 designates a body having side folds 2, each of which is formed with a vertical slit 3. The bottom of the body has a lower inclosing flap 4:, having an extension 5 and a laterally-projecting tongue 6, the said extension and tongue being primarily constructed of double the width required when the parts are properly arranged for folding,

as will be presently set forth. The upper part of the body has a closing-flap 7, having a tongue 8 with an extension 9, the extension 9 being folded over to reinforce the said tongue.

In folding the parts the extension 5 and tongue 6 of the lower flap 4. are doubled over on the line 10, thus arranging on the said flap 4 a laterally-projecting tongue which when in looking position, as shown in Fig. 3, is folded on the line 11. The tongue 8 is also made in double form,and with the extension 9,is folded on the line 12, and the said extension then brought to bear over the said tongue, thus materially reinforcing the tongue in connection with the closing-flap for a purpose which will be presently set forth. After the parts are thus arranged the side folds or flaps 2 are brought inwardly over the body 1 and the slits 3 coincide. The lower fold or iiap 4 is then brought upwardly; but previous to this operation an eyelet 13 is secured in the folded extension 5 and projected outwardly. The eyelet 13 is covered at the rear by the innermost fold of the part through which it is passed, so as to protect the contents of the envelop and prevent rubbing of the latter against the said eyelet. The outer part of the eyelet is exposed at the back of the envelop when the parts are all assembled or arranged in permanent position. The tongue 6 in its double form is then passed through the coinciding slits 3. The parts when thus assembled are secured by suitable adhesive material and are ready for use, and after an inclosure has been located in the envelop the closing-flap 7, with its tongue 8, is brought down and the projected portion of the eyelet 13 is passed through an opening 14. in the said tongue 8 and upset to securely fasten the said closing-flap. WVhen the tongue 6 is inserted through the slits 3, a sufficient opening is provided to permit the insertion of a resisting base or implement to facilitate the upsetting of the eyelet 13. When all the parts of the envelop are sealed, as set forth, it will be impossible to open the same with out detection, and a safety construction is thereby provided for the transportation of mail-n1atter.

It is obviously apparent that many minor changes in the details of construction and arrangement of the several parts might be made and substituted for those shown and described without in the least departing from the nature or spirit of the invention.

Having thus described the invention, what is claimed as new is A safety-envelop comprising a body with end folds or flaps having slits therein adapted to coincide, a lower flap with a laterally-projecting tongue, and an extension carrying an eyelet, the said tongue being passed through the coinciding slits in the end folds or flaps, and a closing-flap having a double tongue with an opening therein to engage the said specification in the presence of two subscribeyelet, the said tongue on the lower flap being Witnesses. ing inserted in the slits in a longitudinal plane and said slits forming means for as- JOHN RILEY sisting in upsetting the eyelet, substantially WVitnesses: as described. 13.
